4 geoid
The equipotential surface in the gravity field of the Earth, which coincides with the undisturbed mean sea level (MSL) extended continuously through the continents.Note.— The geoid is irregular in shape because of local gravitational disturbances (wind tides, salinity, current, etc.) and the direction of gravity is perpendicular to the geoid at every point.(AN 4; AN 14/I; AN 14/II; AN 15; PANS-OPS/II)Official definition added to: AN 4 by Amdt 51 (05/11/1998), AN 14/I & 14/II by Amdt 2 (1997), AN 15 by Amdt 29 (06/11/1997).Эквипотенциальная поверхность в гравитационном поле Земли, совпадающая с невозмущённым средним уровнем моря (MSL) и его продолжением под материками.Примечание. Геоид имеет неправильную форму вследствие местных гравитационных возмущений (ветровых нагонов, солёности, течений и т. д.) и направление силы тяжести представляет собой перпендикуляр к поверхности геоида в любой точке.International Civil Aviation Vocabulary (English-Russian) > geoid
